I'm trying to make an Item/trigger where:
When the counter reachs 0 , then send me emails.
I'm using perfmon for this.
The counter i'm using is :
PERF_COUNTER["\\HQPC30599\MSSQL$DBA_SQL:General Statistics\User Connections"]
This is the expression i'm using:
{MAQUINA DBA TESTE:PERF_COUNTER["\\HQPC30599\MSSQL$DBA_SQL:General Statistics\User Connections"].last()}=0
but when I check the trigger, it says INACTIVE:
With the error message unsuported Item Key.
Why is this happening? has anyone passed for this?
Ignore the triggers until your items work. In this case, the item does not work.
The error tells you that the item key is wrong. You used PERF_COUNTER as the key, but the correct key is perf_counter - you uppercased it for some unknown reason.

Trying to setup Zabbix to show incomming login failures by syslog log files. I try to create an trigger which triggers when the last value occurs in the last 5 minutes of x amount of items.
The following expression is created:
Code:
count(/Syslog server/log[/var/log/failedlogin.log],5m,"like","last(/Syslog server/log[/var/log/failedlogin.log],#0)")>3
Also the following does not work:
Code:
count(/Syslog server/log[/var/log/failedlogin.log],5m,"like","{ITEM.LASTVALUE}")>3
I'm sure the count function works like it should be, when i fill in de variable manually the item does trigger.
But when i try to get a value out of an other items which is containing the data is seems to not work.
Could someone tell me if this is even possible? Thanks and greetings.

I'm trying/failing to change the value of a field in a table after it is inserted using the "after insert" trigger. Something like this...
EditRecord
SetField
Name orig_id
Value = [mytable].[id]
End EditRecord
This doesn't seem to work.
USysApplicationLog gives...
SourceObject = mytable.AfterInsert
DataMacro InstanceID = {489D5697-5247-44A8-AE3C-3773A25F72E5}
Error Number = -20335
Category = Execution
Object Type = Macro
Description = EditRecord failed because the default alias represents a record which is read only.
The field is not read only. After the fact I can edit it just fine. I don't know what the "default alias" is nor what that even means.
If the trigger can't do this, can you think of another way to accomplish the same thing ?
You don't want to use the AfterInsert, since then the record is already saved, and tucked away nicely, and everything you need to change in that record is assumed to have been done. In fact, the default context will cause the record in question to be read only. You CAN get around this by pulling the record again, (looking up a record), but if you modify it again then all of the triggers for that record will fire again.
So I ONLY suggest you use this event to sum() or add/edit OTHER tables, but not the record that was just edited and saved.
If you need/want to update this current record, then move your "edit" or "modify" code to the "BeforeChange". This event not only lets you edit/modify right before the save (and thus preventing endless loops in which the update triggers fire again and again), but the CURRENT record is in full context, and you don't even need any "edit record" command, since you have the fresh un-saved record right in context. You thus can use SetField without the need for EditRecord.
So, the AfterInsert is really too late here, and if you could modify the record in that event, you will cause the AfteUpdate event to fire again if you do use a workaround.
Now, if you use BeforeChange, it will fire for both insert and edits (change). So, if your code really only needs to run when inserting, you can check this status by using
If [isinsert] = True then
Edit
Also, it looks like your code is attempting to save (capture) the previous value, and if it is, then you can use:
[old].[id]
Of course this does not make too much sense for "id", since that is usually an autonumber PK column, but for grabbing other values during an update in the BeforeChange event, you can certainly test + inspect the previous (old) values.
I have a table with a field which is of a calculated type and contains the following expression:
IIf(IsNull([OrderValue]),[TotalPhaseLabourCost]-[DefaultOrderValue],[TotalPhaseLabourCost]-[OrderValue])
For some reason when I go to open the table in any view it throws the error:
"There was an error compiling this function.
The Visual Basic module contains a syntax error.
Check the code, and then recompile it."
However, I have this database currently open on two laptops, one works fine and the other has this issue. I have checked both db's refs and they also match up.
That's a bit vague, so I can only make guesses.
Try to compile the code as the error message says.
check if you have any function with the same name as your field
Try replacing IIf(IsNull([OrderValue]), by IIf([OrderValue] is Null,
You probably miss the leading equal sign:
=IIf(IsNull([OrderValue]),[TotalPhaseLabourCost]-[DefaultOrderValue],[TotalPhaseLabourCost]-[OrderValue])
Or you could use:
=[TotalPhaseLabourCost]-Nz([OrderValue],[DefaultOrderValue])
For me there was some problem with some fields (it showed an error message #NAME? in some of the fields (date, number) in the 'new' record).
For me it worked to close the table, right-click it and open in design view.
For each of the fields with problems, I choose the data type (that was already shown) again from the drop down menu (so, same data type!).
Save.
Then it didn't give the error messages anymore.
I am a beginner in zabbix agent.I would like to know if the below trigger is syntactically correct? If yes then how do I know if the trigger is fired ?
I am not able to receive email notifications.Kindly help me .
{MDMCenter:eventlog[761848].iregexp("Job.Execute() failed. (ex.Message = System.Exception: Exception: Failed in Batch: [1] of \[[0-9]*\] ---> System.Exception: Exception: Failed in Batch: [1] of \[[0-9]*\]] ---> System.IO.IOException: The network name cannot be found.")}
The expression as you have it here seems to be invalid - looks like you have accidentally added some example value inside the function parameters.
You can look for the trigger firing on the dashboard or in the Monitoring -> Triggers page.
In general, before even looking at triggers, verify that data is coming in and that the values match your expectations. If some trigger still does not seem to work, always provide exact trigger expression and a few example values, as well as all the things you have checked (server being running, item values being recent and so on).
I have an item of type float, but sometimes a string is received in case of error instead of a number. How can I make a trigger regexp to fire in this case?
I have no idea now to check for "wrong data type".
Actually this is by design and what I'm trying to do is this: if the data gathering fails, I send an error message in order to see it on zabbix end.
I tried with nodata(0), but this doesn't seem to work.
In you case zabbix will not store the "wrong" value for the item. And if you don't care what the string is then you can just setup a trigger for "nodata" for the period of your interval. Look in the triggers manual and search for the "nodata".
Edit: scratch that, didn't read the whole question ....
Edit2: if you are certain that this is not working by design and not because your trigger interval misses the data interval, then you can try to catch the unsupported status. There is an open request for the functionality, but you can setup a side script similar to this. Or you can wrap the monitored item on the node into a UserParameter script that reads the value and prints -1 or something if it is not a number. Then proceed with a normal numeric trigger.
